摘　　要：针对单核CPU需要同时处理多个任务的问题,考虑到以STM32F4单核处理器为核心的自行车里程表的多任务管理需求,采用FreeRTOS操作系统来实现自行车里程表的数据测量任务、LCD显示任务以及两个定时器任务。结果显示,自行车里程表能有效计算并在LCD中显示自行车的速度和里程数,具有良好的交互性。Aiming at the problem that single-core CPU needs to process multiple tasks at the same time,considering the multi-task management requirements of bicycle odometer with STM32F4 single-core processor as the core,the FreeRTOS operating system is used to realize the data measurement task,LCD display task and two timer task of bicycle odometer.The results show that the bicycle odometer can effectively calculate and display the speed and mileage of the bicycle in the LCD,and has good interactivity.
